Note 1 — VISION AND SCENT OF VULTURES.

When I said "Wilson" above I find I was slightly mistaken. I remembered reading it long ago in the first edition I possessed of this writer's works—the little four-volume set edited by Prof. Jameson for "Constable's Miscellany," Edinburgh, 1831, and taking down the book now, which I have not opened for years, I find the passages in question (Vol. iv, pp. 245 et seq.) form part of an appendix drawn from Richardson and Swainson's "Northern Zoology," and that the real authority is Audubon.
